It's not that tricky, is it?
Read the CSV file, split out the fields.
Get or create the category
Get or create the subcategory
Get or create the product
in code:
import csv
data = csv.reader(open('/path/to/csv', 'r'), delimiter=';')
for row in data:
category = Category.objects.get_or_create(name=row[0])
sub_category = SubCategory.objects.get_or_create(name=row[1],
defaults={'parent_category': category})
product = Product.objects.get_or_create(name=row[2],
defaults={'sub_category': sub_category})
